Where Cognism Falls Short
Cognism is a data provider, not a prospecting tool. It gives you contact information but does nothing to help you prioritize, personalize, or reach those contacts.
No outreach or messaging capabilities. After pulling data from Cognism, you still need a separate email tool, dialer, and messaging strategy.
No learning from outcomes. Whether your team closes 0% or 50% of Cognism leads, the platform offers the same data quality and recommendations next month.
Intent data requires a separate Bombora integration at additional cost, rather than being natively built into the prospecting workflow.
Primarily strong in EMEA. North American and APAC coverage, while improving, does not match the depth of Cognism's European dataset.
Pricing is seat-based, which means costs scale linearly with team size even though each rep accesses the same underlying database.
Where Greenway Wins
Greenway is a complete prospecting engine. Data, scoring, research, personalization, and delivery are all handled autonomously.
No additional tools needed. Cognism requires you to bolt on outreach tools, dialers, and personalization software. Greenway handles the full workflow.
The learning loop continuously improves targeting. Cognism delivers the same static data regardless of how your campaigns perform.
115+ buying signals are built in at no additional cost. Cognism charges extra for Bombora intent data.
Results-based pricing means you pay for qualified leads delivered, not database seats.
Global coverage with consistent depth. No regional gaps that require supplementing with other data providers.
